I recently got around to working on some nintendo vs boards that I have had for over a year. smb and hogans alley worked fine, excitebike and duck hunt did not. I tested the dh and eb chips in the known working boards.
please correct me if I am wrong with the next step in my testing theory.
the ppu chips control the colors? so if I try the duck hunt or excitebike ppu chips with smb or hogans alley I should get the game to come up with wrong colors, if the ppu chips are ok. from there I can be sure My roms are bad.
If the smb/ha does not work with the dh or eb ppu chips then I should assume the ppu is bad and then test the roms with a known working ppu from smb/ha and see what I get.
does all that make sense? is there an easier way to figure out the problem?
they all use the same cpu, right?
I am not that worried about getting excitebike to work, but I really want to play some duck hunt.
thanks.
